Mercury poisoning is a type of metal poisoning due to exposure to mercury. [3] Symptoms depend upon the type, dose, method, and duration of exposure. [3] [4] They may include muscle weakness, poor coordination, numbness in the hands and feet, skin rashes, anxiety, memory problems, trouble speaking, trouble hearing, or trouble seeing. [1]
The human fetus and medically compromised people (for example, patients with lung or kidney problems) are the most susceptible to the toxic effects of mercury. [9] Mercury poisoning can also occur outside of occupational exposures including in the home.
Acrodynia is a medical condition which occurs due to mercury poisoning. The condition of pain and dusky pink discoloration in the hands and feet is due to exposure or ingesting of mercury. It was known as pink disease (due to these symptoms) before it was accepted that it was just mercury poisoning. [1]
A side reaction of this catalytic cycle led to the production of a significant amount (about 5% of the outflow [13]) of the organic mercury compound methylmercury. [14] As a result of the catalyst change, this highly toxic compound was released into Minamata Bay regularly between 1951 and 1968, when this production method was finally ...
The toxic effects of arsenic, mercury and lead were known to the ancients but methodical studies of the overall toxicity of heavy metals appear to date from only 1868. In that year, Wanklyn and Chapman speculated on the adverse effects of the heavy metals "arsenic, lead, copper, zinc, iron and manganese" in drinking water. They noted an ...
Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. [1] Chelation therapy has a long history of use in clinical toxicology [2] and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks, including the mobilization of ...
A 2003 monograph on mercury toxicity from the WHO concluded that dental amalgam contributes significantly to mercury body burden in humans with amalgam fillings and that dental amalgam is the most common form of exposure to elemental mercury in the general population, constituting a potentially significant source of exposure to elemental mercury.
[4] [1] Like methylmercury, ethylmercury distributes to all body tissues, crossing the blood–brain barrier and the placental barrier, and ethylmercury also moves freely throughout the body. [5] Risk assessment for effects on the human nervous system have been made by extrapolating from dose-response relationships for methylmercury. [1]
